Add automatic java lib mappings

[neokoenig]

Would make plugins more powerful if there was a way to have /plugins/pluginName/lib/ automatically added to the this.javamappings: that way you could easily deploy javalib based plugins without additional configuration.

yay? nay?

[perdjurner]

Not familiar with this, can you give me a real world example?
Can the plugin itself add the mapping or is that impossible currently?

[neokoenig]

i.e, lets say you wanted to make a bCrypt plugin. The easiest way is via

this.javaSettings = {
    	LoadPaths = ["miscellaneous"]
  	};

in config/app.cfm

Chuck your .class file in, the do bCrypt = CreateObject( "java", "BCrypt" );

So what I'm saying is it would be great if /lib or /java as auto-added to this.javasettings if it exists: that way you don't need to change code outside of the plugin to use it.

The more I think about this the more I like it: it means you could very easily add plugins which just expose java libs and add a few convenience functions. Bycrypt, iCal4J, MarkdownJ would be some easy wins for new plugins (I've actually already written these too).

I'll implement unless there are any strong objections.

I thought you could use a path on CreateObject() but I've just checked and it's a Lucee only feature, so I agree this would be useful.

I got this to work but recursing over plugin directories and adding them all to JavaSettings.LoadPaths. Then all a plugin author has to do is place the java file directly in a plugin directory or subdirectory.

[neokoenig]

Cool, that was pretty much my thinking. Have you done this got the code already? If so that would be fab, otherwise I'm happy to do it

[andybellenie]

No problem

param name="this.javaSettings.loadPaths" default=ArrayNew(1);
for (file in DirectoryList(path=ExpandPath("/#application.$wheels.pluginPath#"), recurse="true", filter="*.class|*.jar|*.java")) {
	ArrayAppend(this.javaSettings.loadPaths, GetDirectoryFromPath(file)); 
}

It needs to go in /wheels/events/onapplicationstart.cfm somewhere so as not to override any paths the user may have set themselves

[neokoenig]

hmm. I can get the folder path into the loadpaths array, but for the life of my can't work out why the .class etc files refuse to load. @andybellenie you're using this in lucee 4.5.x?
